Abstract
The utility model provides a leakage protection plug with temperature protection. Heat conduction sheets are respectively connected between a phase pole copper bolt and/or a zero pole copper bolt of the plug and the casing of a temperature sensor. The casing and the heat conduction sheets are insulated from each other. When high temperature caused by bad contact of the copper bolts of the plug and a socket and other reasons is produced, the electrical connection of the leakage protection plug and the socket can be timely and effectively cut off through a temperature sensor, a control circuit and a switch breaking mechanism, so as to avoid electrical shock casualties and electrical fire accidents.
Description
Technical field
The utility model relates to Electrical Safety resist technology field, particularly a kind of leakage protecting plug with temperature protection.
Background technology
existing leakage protecting plug with temperature protection function, generally that temperature sensor is fixed on the wiring board of belt switch control circuit, or temperature sensor is fixed on the temperature sensor fixed head, because the copper latch of plug and the heat transmission between temperature sensor are to realize by the low air of the coefficient of heat conduction, make the temperature on the copper latch of plug can not pass to timely and effectively temperature sensor, temperature sensor is slow to the reflection of the temperature rise on the copper latch of plug, when the temperature fast rise on the copper latch of plug, the temperature of temperature sensor does not also reach set point, the switch disjunction mechanism can not produce the protection action reliably, make socket, leakage protecting plug is burned, very easily cause the generation of electric shock injures and deaths and electrical fire accident.
Summary of the invention
The purpose of this utility model is to provide a kind of leakage protecting plug with temperature protection; in the copper latch that plug occurs and socket loose contact etc. during former thereby generation high temperature; can cut off timely and effectively the electrical connection of leakage protecting plug and socket, make its use more safe and reliable.
the technical solution that the utility model proposes is such: a kind of leakage protecting plug with temperature protection, comprise upper casing, lower casing, temperature sensor and fixed head thereof with shell, the phase utmost point of plug and zero utmost point copper latch, the switch disjunction mechanism, the wiring board of control circuit is housed, temperature sensor is located near the phase utmost point and zero utmost point copper latch, the switch disjunction mechanism passes through temperature sensor, control circuit is done the disjunction action to the power supply of plug copper latch, also be provided with conducting strip, between the shell of the phase utmost point copper latch of described plug and/or zero utmost point copper latch and temperature sensor, be connected with respectively conducting strip, mutually insulated between described shell and conducting strip.
The material of described conducting strip can be selected copper material or high pottery or the high silicon rubber of the coefficient of heat conduction of the coefficient of heat conduction.The sheathing material of described temperature sensor can be selected engineering plastics or high pottery or the high silicon rubber of the coefficient of heat conduction of the coefficient of heat conduction.
Compared with prior art, the utlity model has following beneficial effect:
The temperature of the copper latch of plug is mainly to be directly delivered on the shell of the temperature sensor that contacts with it by the high conducting strip of the coefficient of heat conduction, and the transmission of temperature is the most direct, most effective, fastest.Therefore when the temperature rise of the copper latch of plug is too high, conducting strip effectively passes to temperature sensor by temperature rise fast, and when temperature reached the operating temperature of setting, temperature sensor passed to control circuit by signal, the action of control circuit control switch disjunction mechanism, by the dump of plug.Thereby effectively protect plug, socket not to be burned, avoid causing the generation of electric shock injures and deaths and electrical fire accident.Improve the usage safety performance of leakage protecting plug.
The accompanying drawing explanation
Fig. 1 is a kind of decomposing schematic representation with leakage protecting plug of temperature protection of an embodiment of the present utility model.
Fig. 2 is the mounting structure schematic diagram that leakage plug shown in Figure 1 is removed lower casing.
Embodiment
By following embodiment, the utility model is further elaborated.
Referring to Fig. 1, shown in Figure 2, a kind of leakage protecting plug with temperature protection mainly is comprised of phase utmost point copper latch 5, the zero utmost point copper latch 4 of plug, switch disjunction mechanism 3, the wiring board 2 that control circuit is housed, phase utmost point conducting strip 9, zero utmost point conducting strip 8 of upper casing 1, lower casing 10, temperature sensor 7, temperature sensor fixed head 6, plug.Wherein an end of phase utmost point conducting strip 9 is connected with the phase utmost point copper latch 5 of plug, can 71 direct contact heat transfers of the other end of phase utmost point conducting strip 9 and temperature sensor 7, one end of zero utmost point conducting strip 8 is connected with the zero utmost point copper latch 4 of plug, the other end of zero utmost point conducting strip 8 and can 71 direct contact heat transfers of temperature sensor 7.Temperature sensor 7 be arranged on fixed head 6 and be positioned at the phase utmost point copper latch 5 of plug, plug zero utmost point copper latch 4 near.The material of phase utmost point conducting strip 9 and zero utmost point conducting strip 8 can be selected copper material or high pottery or the high silicon rubber of conductive coefficient of conductive coefficient, and the material of temperature sensor shell 71 can be selected engineering plastics or high pottery or the silicon rubber of conductive coefficient; The condition of selecting is the necessary mutually insulated of conducting strip and temperature sensor shell.In the present embodiment, phase utmost point conducting strip 9 and zero utmost point conducting strip 8 are selected copper material, and temperature sensor shell 71 is selected the engineering plastics of insulation.
The course of work of the present utility model: leakage protecting plug in use; in case plug and socket loose contact cause the copper latch temperature promotion of plug; conducting strip 8,9 passes to temperature rise temperature sensor 7 fast; when temperature reaches the operating temperature of setting; the signal that temperature sensor 7 produces is passed on the wiring board 2 with control circuit by wire of output terminal 72; 3 actions of control circuit control switch disjunction mechanism, by the dump of socket phase, zero utmost point copper latch 5,4.Thereby effectively protect plug, socket not to be burned, avoid causing the generation of electric shock injures and deaths and electrical fire accident.
